Measurement gap sharing between radio resource management and positioning reference signal measurements

By introducing a carrier-specific scaling factor (CSSF) in the 5G system, the resource allocation between positioning and mobility measurements is optimized, resolving the conflict between PRS and RRM measurements and improving measurement efficiency and resource utilization.

AI Technical Summary

⚠Technical Problem

In 5G wireless communication systems, user equipment (UE) experiences measurement gap conflicts and resource waste when performing Position Reference Signal (PRS) measurements and Radio Resource Management (RRM) measurements, resulting in low measurement efficiency.

⚗Method used

By introducing a carrier-specific scaling factor (CSSF), based on factors such as PRS periodicity, measurement gap periodicity, silent bitmap, and silent type, positioning and mobility measurements within measurement gaps are optimized, enabling flexible scheduling and resource sharing of measurement gaps.

🎯Benefits of technology

It improves the measurement efficiency of the UE, reduces conflicts and resource waste in measurement gaps, and enhances positioning accuracy and the efficiency of radio resource management.

Abstract

Techniques for wireless positioning are disclosed. In an aspect, a user equipment (UE) receives a positioning reference signal (PRS) configuration indicating at least a muting bitmap, a muting type, a PRS periodicity, or any combination thereof; receives a measurement gap configuration indicating one or more measurement gaps and a measurement gap periodicity; and performs a positioning measurement, a mobility measurement, or both, within the one or more measurement gaps based on a carrier-specific scaling factor (CSSF) for the one or more measurement gaps, the CSSF determined based on the PRS periodicity, the measurement gap periodicity, a size of the muting bitmap, the muting type, or any combination thereof.
